GUARD FOB COIN-COLLECTION BECEPTACLES.

Application flea my s, 192s. serial m. 649,421.

This invention relates to guards for coin accompanying" drawings and subsequently 50 collection receptacles and has for its primary object to provide a simple and eiective device of this character which may be readily applied and used in connection with coin banks or safes of various types to prevent the extraction of coins therefrom through the coin receiving slot while permitting of the ready insert-ion of coins through said slot into the bank or receptacle.

It is another object of the invention to provide a yieldable guard element extending continuously along the inner side of the coin receiving` slot and locally displaceable by pressure of the coin inserted through said slot while substantially closing the remaining portion of the slot against the possible extraction of a coin therethrough.

In one embodiment of the present improvements.` the novel feature of the invention is primarily characterized bv the intertittinar relation of the convolutions of two parallel coil springs, such interfitt-ing parts of the slot. These spring convolutions are so spaced vfrom each other that when coins of various sizes are inserted through the slot, only the convolutions directly engaged by the coin are relatively displaced to such an extentas to permit of the passage of a coin through the slot. said intertitting convolutions suhstantially closing the remaining portion of the slot and acting as a barrier against the withdrawal of a coin therethrough.

It is a further general object of the invention to provide a device for the above purpose which is simple and inexpensive in its construction so that it will not materially add to the manufacturing cost of such coin banks or safes and which will also be exceedingly durable and therefore, not liable to get out of order.

With the above and other objects in view, the invention consists in the improved guard device for coin collection receptacles and in the torni, construction and relative arrangement ot the several parts, as will be hereinafter :more fully' described, illustrated in the tions over the inner side ofthe coin receiving` incorporated in the subjoined claim.

In the drawing wherein I have illustrated one simple and practical embodiment of the invention and in which similar reference characters designate corresponding parts l throughout the several views:

Figure l is a fragmentary perspective view of a coin collection receptacle such as a portable bank or safe, showing the coinentrance slot in one wall thereof provided with `my improved guard device;

Figure 2` is a detail view of the guard,

the housing walls :tor the same being shown in section;

`Figure 3 is a transverse section taken on the line 3--3 of Figure 1;

Figure 4 is a similar view illustrating the y manner in which the resilient guard members are relatively displaced upon the insertion ot a coin into the receptacle; and,

Figure 5 is a bottom plan view showing the resilient guard springs locally displaced from normal position by a coin.

Referring in detail to the drawing, for purposes ot illustration I have shown a part of the bank 5 which may be of any desired torrn and is provided in one of its walls with the coin entrance slot 6.

To the inner side of the wall of the `bank structure `and extending longitudinally of the slot 6, a sheet metal housing 7 is suitably secured. As herein shownthe bottom of` vided with a longitudinally extending slot` l1 which is of the same length as the slot 6 Vand in alignment therewith.

Within the housing just descrlbed a pair of resilient coil springs 12 are arranged, said springs having their coil seiveluties' ex# supporting the saine against the under side of the top of the receptacle and said housing being of zt Width to restrict the separation of said coil springs beyond the point of frictionally engaging a coin inserted throu h the slots between said springs whereby istortion of the convolutions of the springs is prevented, said springs being disposed in the housing with their convolutions in overlapping relfttion and adapted to be spread apart into engagement with the side Walls of the housing by a coin inserted through said slots;

In testimony that I claim the foregoing as my invention, I have signed my name hereunder.
